The affected file may be 0 KB or smaller than expected. This is most often caused by a problem while downloading the JCR file. The file should be downloaded again, making sure that the process has finished correctly.
The most common cause here is computer viruses. Perform a virus scan using available and up-to-date anti-virus software. Some antivirus vendors also provide free online scanners. However, it is important to scan the entire system, not only the file JCR or the program directory. Sometimes virus-infected JCR files cannot be recovered, so make a backup in advance.
Older version of JCR file may not always be supported by the latest software version. These problems are known and are often very easy to fix using the software developers's website.
There can be many reasons for this. Repairing is very dependent on the file type. Some programs offer the option of recovering data from damaged JCR files. You can restore the file from a backup or use help.
When reading, a message appears that the file was encrypted or corrupted. The encrypted JCR files cannot be played on other computers than the one on which they were encrypted, they must be decrypted before using on another device.
The operating system protects files in some locations (e.g. the root of the system partition) against unauthorized access. The problem is only writing to the file, not reading it. Copying the JCR file to another location will fix the problem.
This can happen on a file that does not support multiple access. In this case, the JCR file is blocked by the first application to open it. Running programs (including those in the background) should be verified. Sometimes you have to wait for the session to the file JCR to close. Antivirus programs or a backup being made may lock the file for a while without the user's knowledge. If this does not work either, restart the device.
